You *are* confused, but for a different reason. GF(2^255-19) is the
underlying field, not the curve defined over that field. There are
many different elliptic curves over that field, but we only refer to a
specific one as Curve25519.

Consider P512 and E521. Both use the same field, but the curves are
quite different.
